CHARLES LIEBE, OF NEV YORK, N. Y.

FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 475,581, dated May 24,1892.

Application filed March 26, 1892. Serial No. 426,563.

To all whom it may concern.-

Be it known that I, CHARLES LIEBE, of New York city, in the county andState of New York, have invented a new and Improved Fastening Device, ofwhich the following is a full, clear, and exact description.

My invention relates to improvements in fasteners, and is an improvementon the device for which Letters Patent of the United States No. 470,246were issued to me March 8, 1892.

The object of this invention is to make an exceedingly-strong andeasily-adjusted fastener, which may be used to fasten the ends of twoabutting pieces together, or which may be used to fasten any adjacentparts of furniture or other articles, and which will make a doubleconnection between the two parts, so that in case one of the connectingportions is broken the other will hold the parts together.

To this end my invention consists in a fastener the construction ofwhich will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective View of the fastener embodying my invention,showing its application to two separable pieces placed at right anglesto each other. Fig. 2 is a front end view of the fastener. Fig. 3 is asection on the lines 3 3 in Figs. 2 and 4, and Fig. 4 is a rear end Viewof the device.

The fastener is provided with a fiat bedplate 10, having screw-holes 10to facilitate its attachment to an article, and this bedplate has oneend formed into a flange 11, which flange is slotted longitudinally, asshown at 12 in Fig. 4, and a latch 13 is held to swing in the recess orslot 12. 13 extends longitudinally across the bed-plate, being pivotedat its rear end, as shown at 14, and the end of the latch which projectsthrough the slot is formed into a head 15, which has a depending point16, the inner inclined portion of the head serving to facilitate thefastening of the latch, as hereinafter described.

Above the latch 13 and near its free end is The latch (N0 model.)

pivoted a cam-lever 17, the lever being pivoted at one end, as shown at18, and near the pivoted end of the lever is a cam 19, which is adaptedto engage or strike the top surface of the latch 13 and force the latterdownward to the limit of its movement, the cam being on the inner sideof the lever, so that the lever may drop outside of the latch.

On the outer side of the flange 11 and near the top of the bed-plate isa'projecting tenon 20, which is enlarged near the middle and has aninwardly-inclined inner and upper portion 21, the inclination beingopposite to the inclination of the inner side of the latch-head 15, andconsequently when the latch-head and tenon are locked in position theseoppo sitely-inclined parts will form What is practically a dovetailconnection and prevent the loosening of the device. A face-plate 22 isarranged at one end of the bed-plate 10 and is adapted to be placedflatwise against the face of the flange 11, the face-plate havingscrew-holes 23 to facilitate its attachment to an article, and in theface-plate is a slot 24, which is adapted to receive the latch-head 15,and the lower wall of the slot is inclined inward, as shown at 25 inFig. 3, so that the inclined inner side of the latch-head 15 may beforced down upon it, and the meeting inclined surfaces will have atendency to draw the two parts 10 and 22 together as snugly as possible.Near the top of the face-plate 22 is a mortise 26 to receive the tenon20, and

the upper wall 27 of this mortise is inclined inward, so as to registerwith the inclined face 21 of the tenon 20.

The fastener is used in the following way: We will suppose that theparts 28 and 29 are to be united. The face-plate 22 is fastened to thepart 29, which is recessed opposite the slot 24 and mortise 26, and thelatch-head 15 and tenon 20 of the bed-plate 10 are thrust into the slot24 and mortise 26, and the camlever 17 is then turned downward at rightangles to the latch 13, as shown in Fig. 1 and as shown by dotted linesin Fig. 3, and this movement of the cam-lever forces the head 15downward, so that its inclined face will abut snugly with the inclinedwall 25 of the slot 24, and the movement of the lever and 100 bed-platewill cause the inclined wall 21 of the tenon 20 to fit snugly againstthe wall27 of the mortise 26. It will be seen then that the bed-plateand face-plate will be locked solidly together, so that they cannotaccidentally become loose.

29 will thus be securely fastened. If through hard usage or for anyreason the tenon 201 should be be broken oif, the latch 13 will hold andthe united parts 28 and 29 will still be held together.

If desired, the bed-plate l0 and the face: plate 22 may be countersunkor let into the The bed plate may be then screwed to the piece 28, andthe pieces 28 and slot and mortise having oppositely-inclined end walls,a bed-plate havinga swinging latch thereon adapted to enter theface-plate slot and an inclined head to fit the slot, aprojecting tenonwith an inclined face to fit the inclined wall of the mortise, and alocking camlever pivoted above the latch and adapted to swing upon thesame, substantially as described.

2. A fastening device comprising a faceplate having a slot and-mortisetherein with oppositely-inclined end walls, a bed-plate having an endflange adapted to abut with the face-plate, a latch pivoted on thebedplate and extending through a slot in its flange, said latch havingan inclined head to enter the slot of the face-plate, a projectingtenonfixed to the bed-plate flange and having an inclined face toregister with the inclined wall of the facetplate mortise, and a lockingcam-lever pivoted upon the bed-plate and adapted to swing against thetop side of the latch, substantially as described.

CHARLES LIEBE.
